SUPPLEMENTARY INFORMATION:

In accordance with section 1413 of the Safe Drinking Water Act (SDWA), 42 U.S.C. 300g-2, and 40 CFR 142.13, public notice is hereby given that the state of Colorado has revised its PWSS program by adopting federal regulations for the RTCR that correspond to the NPDWR in 40 CFR parts 141 and 142. EPA has reviewed Colorado's regulations and determined they are no less stringent than the federal regulations. EPA is proposing to approve Colorado's primacy revision for the RTCR. This approval action does not extend to public water systems in Indian country as defined in 18 U.S.C. 1151. Please see SUPPLEMENTARY INFORMATION, Unit B.

A. Why are revisions to State programs necessary?

States with primary PWSS enforcement authority must comply with the requirements of 40 CFR part 142 to maintain primacy. They must adopt regulations that are at least as stringent as the NPDWRs at 40 CFR parts 141 and 142, as well as adopt all new and revised NPDWRs in order to retain primacy (40 CFR 142.12(a)).

B. How does this action affect Indian country (18 U.S.C. 1151) in Colorado?

EPA's approval of Colorado's revised PWSS program does not extend to Indian country as defined in 18 U.S.C. 1151. Indian country in Colorado generally includes (1) lands within the exterior boundaries of the following Indian reservations located within Colorado, in part or in full: The Southern Ute Indian Reservation and the Ute Mountain Ute Reservation; (2) any land held in trust by the United States for an Indian tribe; and (3) any other areas which are “Indian country” within the meaning of 18 U.S.C. 1151. EPA or eligible Indian tribes, as appropriate, will retain PWSS program responsibilities over public water systems in Indian country.
